VACUUM CLEANER Filed Nov. 24, 1928 Igvexjtof' @s MMM Z, gttorzgcgaPatented Dec. 3U, 1930 v PATENT GFFICE EDWIN JUELSON, OF CHICAGO,ILLINOIS VACUUM CLEANER Application filed November 24, 1928. Serial- No.321,618.

This invention relates to electric vacuum cleaners and has for itsobject the provision of a new and improved device of this characterwhich shall be particularly cheap to manufacture, compact in form, easyto carry about, and convenient to manipulate; the provision of a newtype and arrangement of dust receptacle; the provision of a vacuumcleaner having a new and improved relation of parts.;

1@ while further objects and advantages of the invention will becomeapparent as the description proceeds.

In the drawings accompanying and forming a party of this application lhave illusl5 trated a specimen embodiment of my inventive idea; Fig. 1is a longitudinal sectional View of my complete improved cleanercorresponding to the line 1-1 of Fig. 5; Fig. 2 is a sectional viewcorresponding to the 2G line 2-2 of Fig. 5, but showing the dustreceptacle removed; Fig. 3 is a side elevation of the ydust receptacleremoved and placed upright; Fig. 4 is a` perspective view of thecomplete device; and Fig. 5 is a front elevation of said cleaner. A

My improved cleaner comprises an external sheet-metal casing 1,approximately cylindrical in shape, formed at one side with suitablefeet 2 2 adapted to rest on the floor, and at the opposite side withk asuitable handle 3 located preferably substantially above the center ofgravity of the machine. Secured in and carried by one end (ifv thiscasing is a pump-unit comprising a fan-casing 4 and a motor-housing 5rigid therewith, the fan chamber being provided with a centrifugal fan 6operatively. connected to the motorshaft 7. Formed in the face of saidfan chamber opposite the motor is an inlet opening 8 l0 with whichcommunicates a hose nipple 9 projecting longitudinally outward from oneend of the casing, which is herein denominated 4the front end. ln thepresent embodiment this nipple includes a transparent in spection-window10.

Rigidly mounted at the rear end of this casing is a dust receptaclecomprising a circular end-member 11, a cylindrical wall 12 havingperforations 13, and a second circular end member or wall 14, theperforated portion bem ing covered with filtering fabric 15. A part ofthis receptacle is removable from the casing 1 to enable the removal ofthe litter, namely the circular end member 14 together with more or lessof the side wall portion 12. In the present embodiment the entire sidewall 12 is removable, and when removed con-- stitute's a pail forcarrying the litter to a convenient place of deposit. I have shown theperforated art and the filtering fabric as introduced ibosely into therearward end of the casing 1 and held there by means of suitable catches16. Also I have shown this pail as provided with a hinged bail 17adapted to be folded inside the perforated portion when y the same isattached to the casing 1. The top or brim of the pail is formed with anenlargement or rolled rim 18 which is seated against a rubber ring 19 inair-tight relation,

and the exhaust air escapes through the gap between the pail and casingdue to the loose fit heretofore mentioned as shown by the arrows in Fig.1.

The fan casing 4 is formed at its periphery with an outlet neck 20 whichis connected by 75 a discharge pipe 21 to a non-removable part of thedust receptacle. This pipe leads rearwardly pastthe motor housing 4which is thus located between the fan casing and the dust receptacle;and to render the device ao more compact I have shown said motor asprojecting more or less into the dust receptacle. The far end of thereceptacle is also formed with feet 2a adapted to rest on 4the iioorwhen in operation.

y Electric current is conveyed to the motor by means of a flexible cord25 which when the machine is not in use can be conveniently supported ona suitable rack 26 fastened to the casing l; and a flexible hose 27 isattached 9o to the nipple 9 and leads to a hand nozzle or collectingtool (not shown).

The design of the machine enables all the visible parts to be made ofsheet metal which is economical to work. The pump unit being 95 entirelyconcealed requires no finishing. The dust receptacle being so farexternal and also located at the rear of the motor can be made large soas both to exhibit a large dust capacity and a largeiiltering area. Alsoit is l0@ much easier to empty than a limp bag. It will he understood,however, that the above and other advantages of my improvements can beenjoyed despite many changes in detail and arrangement. For example, theinlet need not be eccentric as here, the dust receptacle can be dividedat another pointin its length than that shown, the inspection window canbe omitted, the design of the fan and casing altered, and many otherchanges made within the scope of my invention.

Having thus described my invention what I claim is:

l. In a vacuum cleaner, in combination a cylindrical casing, floorengaging feet carried by one side thereof adapted to rest on the floorand thereby supportsaid casing with its axis horizontal, a pump unitcarried by one end of said casing, a dust receptacle carried by theother end of said casing, said pump unit comprising a fan casing havingan inlet through the first mentioned end of said first casing, a fan insaid fan casing, and an electric motor operatively connected to said fanand located between said fan casing and said dust receptacle, said dustreceptacle comprising a cylindrical perforated side wall, an imperforateend wall, and filtering fiabric covering the perforations, a dischargeconduit leading from said fan chamber to said dust receptacle past saidmotor, a flexible hose communicating with said inlet, and a carryinghandle attached to that side of said first casing which is opposite saidfeet.

2.
